New Slurry Pump in the Mix


Australian Pump announces a new heavy duty submersible pump is now available with a powerful agitator for pumping thick slurry.  The product is made by Japan’s leading submersible pump manufacturer Tsurumi, and is aimed at the concrete mixing and batch plant market.

The pumps are designed to agitate and mix concrete and also aid in the reclamation of materials from unused concrete at batch plants. The KRS slurry pump series offer capacities of up to 3,250 litres per minute flow, and heads as high as 22 metres.  The complete series includes discharge bores from 80mm (3”), all the way through to 150mm (6”).

The KRS series are fitted with 3 phase, heavy duty 4 pole high efficiency motors with thermal and amperage protection against dry running or overloading.

“The pump has been designed with a top discharge so it suits concrete or slurry mixing” said Aussie Pumps’ Craig Bridgement. “The liquid passing through the pump also cools the motor, making the pump even suitable for use in applications with low water levels.”

Tsurumi Pump developed the product range in response to requirements in US and Japanese markets for super tough pumps for the mining and constructions markets.  Features include a newly developed double mechanical seal with both top and bottom silicon carbide seal faces running in an oil filled chamber for extended life.

The mechanical seal also features a unique “Oil Lifter” developed to enhance seal performance.  The unique design of the mechanical seal enables the “Lifter” to oil the top seal faces, even if the lubricant level drops below manufacturer’s recommendations.  The lubrication cools the seal faces, providing longer life, and reducing wear.

The Tsurumi KRS pump range features a high capacity semi open style impeller to enable a combination of flow and pressure, even in the toughest conditions. The impeller is made from high chrome cast iron for wear resistance, and the suction cover, designed for a long, trouble free life, is made from ductile cast iron.  The shaft seal is a double design, silicon carbide, whilst the pump shaft is 420 grade stainless steel.

Standard equipment includes heavy duty 8 metre cable to Tsurumi’s unique anti wicking block. The anti wicking block prevents the ingress of water into the motor even if the cable is damaged or worn. It is a feature that makes Tsurumi pumps stand out from others in the market.

“The heavy duty KRS series is expected to be of real interest to the cement batch plants, particularly for concrete waste re-cycling,” said Bridgement.  “Water can be removed from sand and gravel pits, leaving the material ready for re-use,” he said.
